To save time/ Product design/Public design

Usually someone press the elevator but leave early because of the short time. The elevator stopped in the corresponding floor but there was none to come in, which wasted us a lot of time. In this design ,we put a infrared transmitter and its receiver in the elevator , when it detect that there is no body on the floor , the pressed button will be automatically cancelled，which save a lot of time.
